Refuse an unversioned database that already has a files table (closes #11)

scan opened any database whose user_version was 0 as empty and ran an unconditional CREATE TABLE files, so a foreign or partially initialized file with a files table failed with the raw SQLite "table files already exists", which explains nothing. createSchema now checks for an existing files table first and, when one is present at version 0, reports the schema-version error telling the operator to remove the file and rescan, matching the README rule that an unrecognized database is fatal.
